Reset Provides Five Tips to Prevent Ransomware

December 7, 2018 Provides Five Tips to Prevent Ransomware

Hikvision Outlines Ways to Prevent Malware


In “Small business: A big target for ransomware,” (SIW) outlines the real threat that ransomware–a type of malware–has on small and mid-sized businesses (SMBs), and provides tips to prevent it.

Cybercriminals are targeting SMBs for a variety of reasons according to the article, including the sheer size of the market, since SMBs “defined as organizations that generate less than $1 billion in annual revenue, account for about 99.9 percent of all companies, 47.5 percent of all jobs and as much as half of annual GDP.”

In 2016, Hollywood Presbyterian Medical Center made a $17,000 ransomware payment using bitcoin. According to the article, many ransomware attacks have occurred since then, with one demand for a seven-figure payment, while the average ransomware demand is about $10,000.

In the article, SIW offers these five tips to prevent ransomware:

  1. Update anti-virus software.
  2. Train employees to identify phishing attempts and avoid unknown attachments and links in emails.
  3. Block macro-enabled malware files from running on Microsoft Office 2016 programs like Word, Excel, or PowerPoint.
  4. Disable autoplay functionality to prevent malware from running on your computer.
  5. Enable automated patches for both your operating system and web browsers.

Hikvision Outlines Tips to Prevent Malware

According to Hikvision’s director of cybersecurity, Chuck Davis, malware is one of the most often used components in cyberattacks. In a recent article, he said: “Two of the most prevalent attack methods are, network scanning and phishing. A typical network scanning attack occurs when a system scans a network (frequently the Internet) looking for vulnerable systems. When it finds one, it will exploit the vulnerability and infect the system with malware.”

IMPORTANT! This model requires non-standard firmware. Do Not Install standard firmware (e.g. v.4.1.xx) on this model. Doing so will permanently damage your system. You must use custom firmware v.4.1.25 from the iDS-9632NXI-I8/16S product page.

The I-series NVR (such as the DS-7716NI-I4) is one of Hikvision's most popular and feature-rich recorders. As such, many firmware revisions have been introduced over the years to continually ensure the product is compatible with the newest technology available. Due to the many revisions, we recommend that the user closely follows the instructions below in order to reduce the amount of time spent as well as the chance of failure.


Database Optimization and Repair

As more affordable IP cameras are introduced over time with greater video resolution and data sizes, more efficient database management also becomes necessary. The introduction of firmware v4.0 brought about a new database architecture in order to be futureproof.


After upgrading to v4.X, the recorder database will need to be converted and optimized. If you are experiencing issues where playback is expected but not found, make sure "Database Repair" is performed as indicated in the procedures and scenarios below.


Preparing the Upgrade

Before proceeding with upgrade, it is recommended that NVR configuration file is exported from the NVR over the network or on to a local USB drive.


Upgrading from v3.4.92 build 170518 or Older

  1. All recorders must reach v3.4.92 before proceeding further. Upgrading from versions before v3.4.92 directly to any version of v4.X will likely cause the recorder to fail.
  2. If the recorder is already at v3.4.92, a full factory default is highly recommended before upgrading to any version of v4.X. There is a high chance of unit failure (requiring RMA) if the unit is not defaulted before upgrade.
  3. After reaching v3.4.92 and performing a full factory default, an upgrade directly to v4.50.00 is acceptable.
  4. After the upgrade is completed and the recorder is reprogrammed, it may be beneficial to perform a Database Repair. For details, refer to the section "Database Optimization and Repair" above.
  5. To verify repair progress, you may refer to the HDD status, or search the recorder log for repair started and stopped entries. Note that while the HDD is repairing, new recordings are still being made, but some existing recordings may not be searchable until repair is complete.
  6. If you continue to observe playback issues after database repair, ensure there are no power, network, or motion detection issues. Should the problem persist, contact technical support.


Upgrading from Any v4.X Build to v4.50.00.

  1. Any v4.X build can be upgraded directly to v4.50.00.
  2. Export configuration is highly recommended before performing the upgrade.
  3. If upgrading from any v4.X version that was not v4.22.005, a Database Repair is recommended. Refer to Step 4 and onwards in the previous section.



Downgrading is not recommended. Due to new features and parameters constantly being added, downgrading may cause the NVR to factory default itself or require a manual default to operate properly.
